The invention relates to windows or doors of carriages and concerns moreparticularly a mounting of pivoted windows which allows a suitableventilation of the passages to be obtained without draught as well as aspecial control for opening the windows.

The arrangements comprise essentially two pivoted windows mounted in thewindow frame and of which a vertical pivot is placed in theneighbourhood of the front part of the windows. An appropriate controlallows the two windows to be displaced simultaneously and in a parallelmanner up to a certain angle of opening corresponding to an appropriateventilation. The connection of the two windows with the support is madethrough the intermediary of a spring box such that once the opening ofthe windows obtained following the maximum angle for ventilation thisopening can be increased until the windows are perpendicular to theirframe by displacing them directly by hand against the action of thespring in the box; the windows returning afterwards under the action oftheir spring when they are freed so far as the angular position set bythe control.

The invention equally relates to various practical details which will bemore particularly described hereinafter.

In the accompanying drawing:

Figure 1 represents in perspective the windows and their controlseparated from the frame;

Figure 2 represents in cross section the windows in their frame in theclosed position;

Figure 3 shows the windows fully opened by hand.

Referring to the drawing it is seen that the arrangements comprise twowindows I, 2 mounted on axes 3, 4 located towards their front part andcarried by the window frame 5.

The windows I and 2 are represented in Figure 3 in the positionperpendicular to the window frame corresponding to the maximum openingby hand. The position indicated in broken lines in Figure 3 correspondsto the maximum opening given by the mechanical control. Also as can beseen from the drawing the windows in the closed position abut oneagainst the other in a manner to assure an airtight joint at their pointof abutment. In the arrangement shown by way of example the frame of thewindow 2 is provided with a rubber tongue 6 which is supported betweenthe bare stop of the frame and the window I. The pivots 3 and 4 of thewindows are integral at their lower end with a cap I of the drum 8; thisdrum 8 being itself mounted so that it can pivot about a shaft 9disposed in the line of the pivot 4 of the window. The shaft 9 isintegral with the lever l E3; the levers ID of the two window supportsbeing joined by a connecting bar H on which the hand control acts aswill be explained hereinafter. The nave 12 of the drum 8 is carried bythe fixing plate l3 on the door and in this nave l2 the shaft 9 canturn, the shaft 9 at its upper part carrying a finger [4 which abutsagainst a stop I on the interior of the drum 8. A spiral spring I6 isfixed at one of its extremities to the nave l2 and at the otherextremity in a slit I? of the drum 8.

The hand control acting on the connecting bar ll of the two windows isconstituted by an end- 15 less screw I3 working in conjunction with ahellcal gear wheel [9 located in a box formed in two halves and fixed onthe door. The screw is integral with a shaft 2| carrying the controlhandle 22 and the wheel I9 is mounted on the shaft I9 which carries alever 23 connected to the connecting bar II by a pivot pin 24. It isseen immediately that by actuating the handle 22 the shafts 9 carryingthe fingers I4 are displaced angularly which allows the operation on thedrums 8 and their caps I by operating window support pivots 3 and 4. Alever 25 which acts as a stop is fixed on the shaft I9 of the helicalgear wheel [9 and limits the displacement of this wheel and consequentlyan angular displacement of the fingers l4 and the support pivots 3 and 4of the windows I and 2. This angular displacement is calculated in orderto obtain a maximum opening corresponding to a good ventilation for thepassengers. However, in order to be able to 5 effect signals with thearm by acting with the hand a supplementary opening movement may begiven to the windows I and 2. If the windows are pushed outwardlydirectly by hand these Windows operate as well as the drums 8 bytightening the springs l6 which allows the Windows to be brought intothe maximum open position. When the windows are freed they automaticallyreturn under the action of their springs into the position in which theyhave previously been set by the mechanical control.

It is quite evident that the mechanical control hereinbefore describedhas only been given by way of example and that it could be replaced byany other appropriate control mechanical, electrical or pneumatic; thiscontrol being nonreversible.

The mounting arrangement of the supporting shafts of the Windows withthe spring box has likewise only been given by way of example. Whatcharacterizes the invention is the ventilation arrangement by means ofpivoted windows the supporting pivots of which placed a little behindtheir front edges are angularly displaced simultaneously by anappropriate control, whilst these same pivots can receive independentlyone from the other a supplementary movement when they are displaced byhand against the action of a return spring which returns them to theposition that they previously had before that supplementary opening.There is equally provided an arrangement which allows the windows to belocked in a closed position in order to prevent the windows being openedwhen the carriage is closed and left by itself. In the practicalconstruction given by way of example this locking arrangement isconstituted by a bar 26 provided at its extremities with buttons havinga circular part 21 corresponding to the rectangular part 23 which in thelocked position engages with the flat surfaces provided on the nave 29of the cap 1. The rod 26 can slide in its support and be manipulated bya handle 30.

I claim:

1. A device for ventilation of passenger vehicles, comprising a doorprovided with two pivotable glass panes, two frames carrying said panes,two supports carried by said door, in each of which one of said framesmay rotate about a vertical axis spaced from the front edge of eachpane, two vertical axles for operating said frames,

two levers for turning said axles, a rod connecting said levers, meansfor moving said rod, comprising a handle, and resilient means connectedwith said frame adapted for returning the latter to the position allowedby the axles after they have been manually shifted from said position.

2. A device for ventilation of passenger vehicles comprising a door withtwo pivotable glass panes, two frames carrying said panes, two supportscarried by said door, in each of which one of said frames may rotateabout a vertical axis at a short distance from the front edge of eachpane, two vertical axles adapted for operating said frames, two leversadapted for turning said axles, a rod connecting said levers, means formoving said rod comprising a handle, elastic means connected with saidframes for returning them to the position allowed by the axles afterthey have been manually removed from said position, and means forpreventing any rotation of said frames in their closed position.

3. A device as claimed in claim 1, in which each vertical axle carries afinger contacting with a stop carried by the corresponding frame wherebythe elastic means may connect the frame to said supports.
